Scientific articles on peptide research, analytical methods, and quality documentation. Every claim cites peer-reviewed literature with PMIDs.
A research overview of epitalon, a synthetic tetrapeptide studied for its relationship to the pineal gland extract epithalamin and effects on telomerase activity in cellular models. Covers molecular structure, the epithalamin connection, and what published research describes about telomere biology mechanisms. For research purposes only.
A technical breakdown of reverse-phase HPLC as the primary analytical method for quantifying peptide purity — how the instrumentation works, how area-percent purity is calculated, and what sourcing teams look for in validated test results. For research purposes only.
A factual analysis of the 2025–2026 FDA enforcement escalation against the research peptide industry. Covers confirmed enforcement events, which compound categories were most affected, and how researchers can adapt sourcing and documentation practices in a high-scrutiny regulatory environment.
A research overview of Selank, a synthetic heptapeptide derived from the immunomodulatory tetrapeptide tuftsin. Covers molecular structure, the tuftsin relationship, GABAergic and serotonergic modulation research, and what published studies describe about its anxiolytic and cognitive mechanisms in experimental models. For research purposes only.
Peptide Sciences closed March 2026. This analysis covers what researchers need from a replacement supplier, where Onward Aminos fits, and how to evaluate alternatives on quality metrics that actually matter.
Peptide Sciences closed March 6, 2026, without warning to customers or partners. A factual breakdown of what happened, the regulatory context, and what researchers should demand from any supplier they evaluate next.
